  • Dissolved oxygen monitoring and control
  • Ammonia based aeration control
  • Phosphorus removal chemical dosing
  • Mixed liquor suspended solids monitoring
  • Sludge wasting control
  • Nitrification and denitrification monitoring
  • Biological phosphorus removal monitoring
  • Effluent monitoring
  • Sludge blanket level monitoring
  • Sludge digestion monitoring
  • pH monitoring and control

The IQ SensorNet is available as a 20-probe network with the 2020 3G controller, a 2-probe network with the 282 controller or a 4-probe network with the 284 controller. All controllers can measure up to 20 parameters, plus secondary parameters such as temperature.

IQ SensorNet 282/284 Controller

IQ SensorNet 282/284 Controllers can connect to 1-4 sensors, allowing up to 20 parameters to be measured. These controllers have an easy-to-read digital display and a USB interface and data logging capabilities for further analysis and troubleshooting. The 282 and 284 can connect to almost any communication protocol including MODBUS TCP, MODBUS RTU, PROFIBUS and PROFINET.

IQ SensorNet 2020 3G Controller

IQ SensorNet 2020 3G Controller allows for the measurement of up to 20 parameters. This completely modular plug-and-play system allows you to monitor and control the process in your wastewater facility continuously and accurately. Benefits include better network visibility and management, early detection of network failures, improved compliance with regulatory targets and cost savings (energy, pump/blower maintenance, labor).

Available modules

IQ SensorNet Wireless Modules MIQ/WL PS

IQ SensorNet Wireless Modules MIQ/WL PS offer cable-free communication for both 282/284 and 2020 3G networks. The MIQ/WL can transmit data up to 100 meters (328 feet) with each primary module being able to communicate with any number of secondary modules. The MIQ/WL makes installation easy, reduces cable/conduit requirements and allows you to measure in challenging locations where cable runs may be difficult. Get the measurement you need in the location you need it with IQ SensorNet and the MIQ/WL modules. 

IQ SensorNet Microcontroller Module

IQ SensorNet Microcontroller Module 2 free IQ SensorNet connections, in module housing, with automatic barometric pressure compensation, USB interface (IP67), Ethernet RJ45 interface (IP 67).
